A couple of years ago I bought about 3,000 floppy disks from a guy in Los Angeles who once ran a PC shareware company. Many of the disks contained shareware downloads from various BBSes in that area, mostly from the late 80s to about 1994. Knowing their historical value, I copied the files off several hundred of these floppies for the sake of history before succumbing to fatigue.
As far as I know this is all shareware or freeware, roughly organized into whatever BBS they downloaded it from. There might be a few adult .GIF files from that era as well as some .FLI animations, so if that stuff offends you, steer clear. Otherwise I'm having a blast loading up .BASIC games from 1982.
